So now both NetMarketShare and StatCounter agree that Windows 10 is the second most popular Windows version, and that achievement has been reached inside the first six months of release, an impressive feat. Microsoft hopes to have its latest OS on one billion devices within three years, and if this trend continues, it's certainly not an impossible target.

We could see a surge in Windows 10 usage as the cut-off date to upgrade for free nears in just under six months time, but we'll know more once we're closer to July.
